I have a ESP8266 D1 Mini Pro wired to a 3787 display and can not get anything to display. I have it wired as shown in my code. I have tried 2 displays and 2 ESP8266. I don't believe I have a hardware problem.

// OPTION 1 (recommended) is to use the HARDWARE SPI pins, which are unique// to each board and not reassignable. For Arduino Uno: MOSI = pin 11 and// SCLK = pin 13. This is the fastest mode of operation and is required if// using the breakout board's microSD card.

#ifdef ADAFRUIT_HALLOWING // HalloWing is a special case. It uses a ST7735R display just like the // breakout board, but the orientation and backlight control are different. tft.initR(INITR_HALLOWING); // Initialize HalloWing-oriented screen pinMode(TFT_BACKLIGHT, OUTPUT); digitalWrite(TFT_BACKLIGHT, HIGH); // Backlight on#else // Use this initializer if using a 1.8" TFT screen: //tft.initR(INITR_BLACKTAB); // Init ST7735S chip, black tab

// OR use this initializer (uncomment) if using a 1.44" TFT: //tft.initR(INITR_144GREENTAB); // Init ST7735R chip, green tab

// OR use this initializer (uncomment) if using a 0.96" 180x60 TFT: //tft.initR(INITR_MINI160x80); // Init ST7735S mini display

// OR use this initializer (uncomment) if using a 1.54" 240x240 TFT: tft.init(240, 240); // Init ST7789 240x240#endif

3787: so promising and so frustrating.There is _nothing_ on the project page except links and tutorials for _other_ TFTs with different pin configurations. I can't believe this is so hard to find.

I just need the simplest: What are the pin outs connected in some example code.There's no documentation of how to hook this up to, for example, a Feather Wing, Arduino, etc.Can anyone please point me to a paragraph or a photo that says:"Hook up these pins from the TFT to (whatever Feather, Arduino, Metro...) and run this code.Can anyone point me to docs for this product?Thank you!
